When you see the manual it's like AR, 99% sure it's restricted, I can't understand why GS5 is prohibed and Colt M4 no restricted.
Sadly, to understand there must be reason. Since reason, for the most part, is derived from rationality... you can only understand something if it has rationality. RCMP would need a valid logical argument, this is not the case. The only understanding is that you just have to accept there is little or no logic in the class system for firearms.
